ACT 2003 Dodge Neon HD/Perf Street Sprung Clutch Kit
The ACT DN4-HDSS is the clutch most Dodge Neon SRT-4 owners should look at first when the original modular clutch is worn out or starting to slip behind a tune, a boost controller or an intake and exhaust package. It keeps a full-face organic street disc, so the car still drives like a normal daily, but it adds a Heavy Duty pressure plate and a lighter flywheel that hold far more torque than the factory unit. If your SRT-4 flares the revs in third or fourth at full boost, or the pedal engagement has crept high, this is the street kit for that problem.
Chrysler built the SRT-4 with a modular clutch: flywheel, disc and cover were assembled as one serviced unit. DN4-HDSS replaces that module with separate parts, which is why ACT lists it as a conversion kit and requires the ACT flywheel that comes in the box. Kit contents are the 600340 XACT Streetlite flywheel, the D017 Heavy Duty pressure plate, the 3001102 Performance Street sprung disc, the RBDN1 release bearing and the ATCP2 alignment tool, plus M8-1.25 x 16 mm pressure plate bolts.
ACT rates the kit at 465 ft-lb at the crank, 47 percent more than the original clutch. The Heavy Duty diaphragm raises clamp load and reduces deflection, while the organic disc uses a high-copper lining for heat transfer with a steel backing for burst strength. Reduced marcel in the disc gives a quicker shift without the bite of a puck disc. The disc is 240 mm (9.4 in) on a 0.9375 in input shaft.
A clutch that will not fully release is a different problem from a clutch that slips, so check the hydraulics first: low or dark fluid, a soft pedal or a leaking slave cylinder point there. Look for oil at the bellhousing seam, since a rear main or input seal leak will contaminate any new disc. Then do a roll-on test in fourth gear from about 2,500 rpm; if the tach climbs ahead of the speedometer, the clutch is slipping. Our slipping diagnosis guide covers the test in more detail.
Our listing title says 2003 Dodge Neon. ACT's application for DN4-HDSS covers the 2003, 2004 and 2005 Neon SRT-4 with the 2.4L DOHC turbo four (2429 cc). It does not fit the non-turbo Neon, and ACT also sells an older DN3-series kit for the SRT-4, so match the full part number DN4-HDSS before you order. If the car has had its modular clutch replaced with another aftermarket setup, send us your year and VIN and we will confirm the parts bolt up. Shipping weight is about 26.3 lb.

Making more power than a street disc can take? The DN4-XTSS Xtreme street kit keeps an organic disc with a stronger plate, and the DN4-HDG6 sprung 6-pad race kit steps up to ceramic for drag and track cars.

ACT recommends 300 to 500 miles of mild engagement, such as city driving, before racing or spirited driving, and warns against overheating the clutch during break-in.
